This class defines toggling facility for both - object's method or variables.

Assume that user provides an object with a two-state field , and methods to Get/Set value of this field. This object enables to switch values via this method when the only thing you know about the field is the name of the method (or method itself) which sets the field. This facility is required in context Pop-Up menu, when the only information about how to toggle a field is a name of methhod which sets it. This class may be also used for toggling an integer variable, which may be important while building universal objects... When user provides a "set-method" of name SetXXX this object tries automaticaly find a matching "get-method" by lookin for a method with name GetXXX, IsXXX or HasXXX for given object.
